## Minestarters Atlas summary

Critical Elements Lithium Corporation provided a preliminary update on its Winter 2026 drill program at the Rose West Discovery in Québec, which successfully extended the known lithium-tantalum mineralization and identified three new spodumene-bearing pegmatitic bodies. The program expanded the main pegmatite body's footprint to 1250m x 800m and returned strong lithium grades, including 1.43% Li2O over 22.00m in hole RW-26-45. These results confirm the project's potential for rapid mineral inventory growth, with all technical content reviewed by a Qualified Person and robust QA/QC procedures in place.

Reasoning: The drill program successfully extended the known lithium-tantalum mineralization at Rose West by a significant margin \(800m east, 400m south\), identified three new spodumene-bearing pegmatitic bodies, and returned strong lithium grades with high grade-width products, confirming the project's potential for rapid mineral inventory growth.

- Positive factor: Significant lateral extension of mineralization

- Positive factor: Discovery of new spodumene-bearing pegmatitic bodies

- Positive factor: Strong lithium grades

- Positive factor: Good grade-width products

- Positive factor: QA/QC procedures disclosed

- Positive factor: QP sign-off

- Negative factor: True width is an estimate, not precisely measured

Facts used in scoring: 14

## Classification and evidence

**True Width Disclosed**

Polarity: positive

Definition: Actual thickness perpendicular to structure is stated, not just downhole length.

Why it applies: The document states true thickness is between 80% to 95% of core length, providing an estimate of true width.

Evidence · text

> the true thickness is between 80 to 95% of the core length

**QA/QC Disclosed**

Polarity: positive

Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\).

Why it applies: The release details QA/QC procedures including standards, duplicates, blanks, and names ALS Minerals as the certified laboratory, with a Qualified Person sign-off.

Evidence · text

> Quality assurance and quality control procedures have been implemented to ensure best practices in sampling and analysis of the drill core samples. Standards, duplicate and blanks were regularly inserted into the sample stream. The drill core samples were delivered, in secure tagged bags to the ALS Minerals laboratory facility in Val-d'Or, Québec. Kenneth Williamson, Géo, M.Sc. Exploration Director at Critical Elements, is the Qualified Person that has reviewed and approved the technical contents of this news release

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Recent drilling extended the main pegmatite body by about 800 meters towards the east and by about 400 meters to the south, significantly expanding the mineralized footprint.

Evidence · text

> extending the main pegmatite body by about 800 meters towards the east and by about 400 meters to the south, thus bringing its overall footprint to 1250 m x 800 m

**Bonanza Intercept**

Polarity: positive

Definition: Exceptionally high-grade zone, well above the deposit-type norm.

Why it applies: Hole RW-26-45 returned 1.43% Li2O over 22.00m, which is an exceptional grade-width product \(31.46 %m\) for lithium.

Reasoning: Intercept of 0.93% Li2O over 12.65m is a moderate lithium grade with a strong grade-width product, extending mineralization.

- Positive factor: Moderate lithium grade

- Positive factor: Strong grade-width product

- Positive factor: Extension of mineralization

- Negative factor: True width is an estimate

## How Atlas produces this analysis

Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
